Description

  

  Verfahren zur Darstellung einer hochmolekularen     Sulfosäure.       Es wurde gefunden, dass man zu neuen,  wasserlöslichen Kondensationsprodukten ge  langen kann, wenn man feste, sauer konden  sierte Kunstharze auf     Formaldehydbasis     einer Behandlung mit Phenol, seinen Homo  logen oder     Substitutionsprodukten    unterwirft  und die entstehende homogene Masse mit  sulfonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet, dass man ein durch Konden  sation von Phenol und Harnstoff mit Form  aldehyd unter     Mitverwendung    von sauren  Katalysatoren erhaltenes Kunstharz in einem  technischen Gemisch     isomerer        Xylenole    vom  Siedepunkt<B>209/220'</B> C löst und bis zur  Wasserlöslichkeit mit sulfonierenden Mitteln  behandelt.  



  Der neue Körper stellt in Form seines       Alkalisalzes    eine schwach gefärbte, amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbwollfärberei    dienen.         Beispiel:     Ein Harz, erhalten durch Kondensation  von 8,5 Teilen Phenol, 25 Teilen Harnstoff,  82 Teilen Formaldehyd und 45 Teilen       Schwefelsäure    2 % wird mit 165 Teilen       Xylenol    bei 70 bis 80   so lange     gerührt,    bis  eine homogene Lösung des Harzes entstan  den ist.

   Man lässt nun zwischen 60 bis 98    165 Teile     konzentrierte    Schwefelsäure zu  fliessen und rührt weiter, bis eine Probe im  gleichen Raumteil Wasser auch in der Kälte  klar löslich ist. Nach Abstumpfen der über  schüssigen Säure mit Natriumkarbonat lässt  sich das lösliche Harz durch     Aussalzen    mit       Natriumchlorid    oder durch Eindampfen als  schwach gefärbte, amorphe Masse gewinnen;  ihre     Lösungen    wirken auf     basische    Farb  stoffe stark fällend, besitzen stark leim  fällende Eigenschaften und färben sieh mit       Ferrichlorid    rotstickig blau.



  Process for the preparation of a high molecular weight sulfonic acid. It has been found that new, water-soluble condensation products can be obtained if solid, acid-condensed synthetic resins based on formaldehyde are subjected to a treatment with phenol, its homologues or substitution products and the resulting homogeneous mass is treated with sulfonating agents.



  The present invention relates to a process for the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of phenol and urea with formaldehyde with the use of acidic catalysts is added to a technical mixture of isomeric xylenols with boiling point <B> 209 / 220 '</B> C and treated with sulfonating agents until they are water-soluble.



  In the form of its alkali salt, the new body represents a weakly colored, amorphous mass. In addition to being a tanning agent, the product can also serve as a wool reservation agent in semi-wool dyeing. Example: A resin obtained by condensation of 8.5 parts of phenol, 25 parts of urea, 82 parts of formaldehyde and 45 parts of 2% sulfuric acid is stirred with 165 parts of xylenol at 70 to 80 until a homogeneous solution of the resin is produced .

   Between 60 to 98 165 parts of concentrated sulfuric acid are now allowed to flow in and stirring is continued until a sample in the same volume of water is clearly soluble even in the cold. After the excess acid has been blunted with sodium carbonate, the soluble resin can be obtained as a pale, amorphous mass by salting out with sodium chloride or by evaporation; Their solutions have a strong precipitating effect on basic dyes, have strong glue-precipitating properties and turn red-sticky blue with ferric chloride.
